POLYOLEFIN MICROSPHERES |
摘要 |
<p>Microspheres comprise a polymer or copolymer including one or more of 1) a plurality of C3 or larger alpha-olefin units wherein the polymer has an average number of branch points less than one per monomer unit, and 2) a plurality of C2 alpha-olefin units wherein the polymer has an average number of branch points greater than 0.01 per monomer unit, the microspheres having an average diameter in the range of 1 to 300 micrometers. Optionally, the polymer of the microspheres can be crosslinked. The microspheres can be prepared by suspension or dispersion polymerization processes using aqueous or organic reaction media.</p> |
